But it gets lonely if that is the only thing you do to reach orgasm. Masturbation is a great way to make sure that a man could reach climax without the help of another man. Unless you have absolutely no idea how to pleasure another man's penis using your hands, then it's actually pretty easy to do, given that you have a pair of balls and shaft yourself. You might think that handjobs are insufficient to make a man bust a nut, but you've never been more wrong in your entire life if you still believe that. But if you still can't figure out what that particular thing is, then you'd be happy to know that it's as simple as giving another man a handjob just so that he could finally reach orgasm without using his own set of hands. And yes, that certainly pertains to something naughty that a man could do to another man. But one thing is for sure, your hands are more than enough to give pleasure to the one you love.
There are much too many ways a person could use their hands, so if these things are listed down one by one, then there would almost be no end to what those things exactly are. With hands, you could draw, write, cook, clean, eat, and even converse with another human being using sign language. It's amazing how many things a pair of human hands could do.
